Scientists have discovered methods in quantum mechanics that break the equivalence principle. That being, according to Einstein (via the article), "the gravitational force we experience on Earth is identical to the force we would experience were we sitting in a spaceship accelerating at 1g." Turns out that with a clever combination of gravitational and electromagnetic boxes and oscillators, well, it ain't so.

No, I'm not sure what to make of it either, but usually when these propeller-heads come up with something really weird, eventually someone else figures out how to make a neat gadget using it. [Whisper]NEAT GADGETS.[/Whisper]
